Abstract

Abstract

There are significant differences in the safety design and operation characteristics between liquid fuel reactor (aqueous homogeneous reactor) and traditional solid fuel reactor, therefore, it is impossible to carry out the safety design of aqueous homogeneous reactor only using the existing safety design methods based on deterministic theories, and probabilistic safety analysis (PSA) technique must be adopted at the beginning of the design period. Due to the differences in fuel forms, safety barriers and mitigation systems, the traditional PSA technique for reactor, which is based on the core damage, cannot be directly applied to aqueous homogeneous reactors. After investigating the requirements and analysis of traditional research reactors, aqueous homogeneous reactors and spent fuel reprocessing facilities at home and abroad, taking the medical isotope test reactor being developed in China as the object, the PSA safety objectives of aqueous homogeneous reactor is put forward, and the PSA technical framework is established, which lays the foundation for the PSA development and safety review of this type of reactor.
